Handheld Measuring Instruments
Owing to their battery mode, the devices can be attached and operated at any pressure measuring point, and directly display or store up to 2,000 values for later evaluations and visualizations.
All data values stored can be exported and displayed on a computer via USB link and by means of the optional VacuGraph software.
Measurement / Display range :
0.1 to 1200 mbar (PV 101)
5 x 10-4 to 1200 mbar (TM 101)
Leybold Model :
Digital PIEZOVAC Sensor PV 101
Digital THERMOVAC Sensor TM 101
